Keep cool

Cool, wherever you go.

Foil-lined insulation and a place for everything — the Cooling Bag keeps temperature-sensitive vials cool between one cool place and the next. We publish the measured cold-retention figure at launch rather than estimating it beforehand.

Travel days, long commutes, warm afternoons — kept steady.

The detail

Everything, in the open.

Insulation
A foil-lined, cushioned wall slows the transfer of heat from the outside in. The exact cold-retention time is published only once it’s independently verified — measured, not estimated.
What it holds
Elastic loops and a clear mesh pocket hold temperature-sensitive vials still and upright, kept in the cool interior away from the outer wall.
On the move
Built for the day a fridge isn’t an option — a commute, a warm office, a weekend away. It slips straight inside the Case.
Warranty & care
Covered by our 90-day promise. Wipe the lining clean; air fully before storing.
The whole kit

Fewer things, made properly.

The Pen, the Case and the Cooling Bag — on their own, or together as the Starter Kit.

Good to know

The Cooling Bag, answered.

How long does the Cooling Bag keep things cool?
The Cooling Bag is insulated to keep temperature-sensitive vials cool away from the fridge — on commutes, travel days and warm afternoons. We publish the exact cold-retention figure with the finished product at launch rather than estimating it beforehand; that number is measured, then printed.
What fits inside?
The bag is sized for the essentials of a considered routine: temperature-sensitive vials held securely, with room for the Pen and its companions. It slips into a tote, a gym bag or a carry-on without announcing itself.
Can I take it on a flight?
The bag itself is ordinary hand luggage. If you travel with any medicine, check your airline's and destination's rules and carry prescriptions in their original packaging — our travel guide covers the practical detail for flying from the UK.
How do I clean and care for it?
Wipe inside and out with a soft, damp cloth and let it dry fully between uses — no machine washing. The full care guide ships with the bag and lives in our Journal.
When can I order one?
The range is new for 2026 and ordering opens soon. Join the list and we'll tell you the moment it does — UK only, 18+.
